j ANSON BALDING, or WHEELING, WEST VIRGINIA.
Letters Patent No. 100,585, datedMarch s, 1870.
IMPROVEMENT IN EXPANSIBLE CORES I'CR CASTING IRON, GLASS, 84c.
The Schedule referred to in these Letters Patent and making part of the same.
To all 'whbin it may concern.-
Be it known that I, Arson BALDING, of Wheeling, in the county of Ohio, and State of West Virginia, have invented a new and improved Expansible Core for Casting Iron, Glass, &c;; andI do hereby declare thatthe following is a full, clear, and exact description of the same, reference being had to the accompanying drawings making a part of this specification, in which- Figure l is partly a side and partly a sectional elevation, and I Figure? is a transverse horizontal section in the linex:v,fig.1. p j I This invention has for its object to enable the cores around which hollow articles are cast to be contracted after filling the mold, so as to facilitate the removal of the cores from within the casting. To this end,
The invention consists in a core, made in two or more separate longitudinal sections, whose adjacent interior edges are beveled away from each other; blocks with beveled edges placed in the intervals between the longitudinal sections; andan apparatus for expanding or contracting the core at pleasure by moving the beveled blocks outward or inward between the longitudinalsections. v V In the drawingsa A A are the longitudinal sections with beveled edges, into which the core is divided.
B B are the beveled blocks placed between the sectious, the blocks and sections being of the same thickness, and the inner and outer sides of each being turned on the same radius, so that the blocks and sectrons may form together a true hollow cylinder when the former are forced outward to their extreme limit, asis the case when the core is set within a mold and molten metal poured around it.
0 is a foot-plate, with an npwardly projecting flange,
c, on which the core is placed when in the mold, the
flange "a of the core entering within the flange c and forming a tight joint.
The foot-plate is connected with the core by a rod,
c, passing horizontally and diametrically through the flanges a c, in sucha manner as not to interfere with the free play of the block B. j
The foot-plate is needed only in glass casting, which is performed by thrusting the core into a mass of the molten metal, the foot-plate then serving as a protection to the interior of the core, as described.
D is a bar, whose upper end is-provided with a bandle, d, and which passes vertically through the middle of the cap of the core, and extends downward nearly to its bottom. r I
Four plates dncar the top and four near the botdrawn downward by the action of the bar and plates.
When the casting has cooled around the moldand shrunk after itsfashion, it is only necessary to draw the Mr B upward to contract the core and enable it to be readily drawn ontof the casting.
Having thus described my invention,
What I claim as new, and desire to secure by Letters Patent, is.
1. The combination'of the sections A, blocks B,
bar D, and plates d, in the manner and for the object specified.
2. The combination of the block B with the roller 7), in the manner and to the end set forth.
3. The combination of the corewith the foot-piate O, in the manner and for the purpose explained.
